[0002] During the PACK operation of square shell battery cell modules, sheet metal connecting pieces need to be welded on the poles. To ensure welding quality, the height of four adjacent poles in a group must be consistent.

[0037] Optionally, it further includes a frame, a laser welding head, and a photographing mechanism, wherein the laser welding head and the photographing mechanism are both located on one side of the first substrate, and the laser welding head, the photographing mechanism and the first substrate are all arranged on the frame.

[0039] Optionally, a telescopic mechanism is further included, and a telescopic end of the telescopic mechanism is connected to the sunshade.

[0040] Optionally, the second X-axis moving assembly includes a first ranging slider on the top of the third rangefinder, a second ranging slider on the top of the fourth rangefinder, and a ranging X-axis guide rail, and the first ranging slider and the second ranging slider both slide in cooperation with the ranging X-axis guide rail.

[0041] Optionally, the first X-axis moving assembly, the first Y-axis moving assembly, and the second Y-axis moving assembly all include a linear guide rail and a linear slider, and the linear guide rail and the linear slider are in sliding cooperation.

[0042] Optionally, the first X-axis moving assembly further includes an X-axis driving element;

[0043] The second Y-axis moving assembly further includes a Y-axis driving element.

[0044] The working principle of this utility model:

[0045] In this embodiment, the first rangefinder is fixedly mounted on the bottom of the first substrate. In other embodiments, the first rangefinder can be movably mounted on the bottom of the first substrate as needed. Since the first rangefinder is fixed, the second, third, and fourth rangefinders are all movable, allowing for adjustment of the distance between them. Since the second rangefinder is mounted on the bottom of the second substrate, in this embodiment, the second rangefinder is fixed to the bottom of the second substrate. The second substrate is connected to the second substrate via a first X-axis movable assembly. Therefore, the second substrate can be moved closer to or further away from the first rangefinder along the X-axis. The linear guide rail within the first X-axis movable assembly is mounted on the first substrate, and the linear slider within the first X-axis movable assembly is mounted on the second substrate. Therefore, the second substrate can be moved relative to the first substrate in the X-axis direction, thereby varying the X-axis displacement of the second and third rangefinders relative to the first rangefinder.

[0046] Since the third rangefinder is connected to the bottom of the second substrate via the first Y-axis moving assembly, the second substrate is provided with a linear guide rail of the first Y-axis moving assembly, and the top of the third rangefinder is provided with a linear slider of the first Y-axis moving assembly, the third rangefinder can move along the Y-axis on the second substrate. When the second substrate moves in the X-axis, both the third rangefinder and the second rangefinder move along the X-axis.

[0047] The fourth rangefinder is connected to the bottom of the first substrate via a second Y-axis moving assembly. A linear guide rail of the second Y-axis moving assembly is provided on the first substrate, and a linear slider of the second Y-axis moving assembly is provided on the top of the fourth rangefinder. Therefore, the fourth rangefinder can move along the Y-axis direction on the linear guide rail of the first substrate, thereby adjusting the position of the fourth rangefinder relative to the first rangefinder in the Y-axis direction.

[0048] The top of the fourth rangefinder is respectively provided with a linear slider of the second Y-axis moving assembly and a second ranging slider via a mounting structure. The second ranging slider can slide along the X-axis direction, and the linear slider of the second Y-axis moving assembly slides along the Y-axis direction, without interfering with each other. The first ranging slider and the second ranging slider are both located on the ranging X-axis guide rail, so that the third rangefinder maintains high linear accuracy when moving along the X-axis, guiding and accurately adjusting the distance between the third rangefinder and the fourth rangefinder.

[0049] The telescopic mechanism can be set on the frame or on the first substrate. When it is necessary to protect the corresponding rangefinder or camera mechanism, the corresponding telescopic mechanism can drive the shading plate to cover the output end of the corresponding rangefinder or camera mechanism to protect the corresponding detection end or lens. When it is necessary to use the corresponding rangefinder or camera mechanism, the telescopic mechanism can drive the corresponding shading plate away from the detection end of the corresponding rangefinder or the lens of the camera mechanism. The laser welding head and the camera mechanism are set on the frame to meet the laser welding, positioning, detection and other processes after ranging. The camera mechanism can select a CCD camera unit. The CCD camera unit can align the position of the battery cell pole, adjust the variable distance measuring mechanism of this solution according to specific requirements, that is, adjust the position of the first rangefinder, the second rangefinder, the third rangefinder, and the fourth rangefinder, so that the height of the four poles can be measured at one time, and the height requirements of the adjacent four poles can be consistent.

[0050] like Figure 2 As shown, the X-axis direction and the Y-axis direction are indicated by the marks. Figure 3 In FIG, the dotted line portion is the detection direction of the first rangefinder, the second rangefinder, the third rangefinder, and the fourth rangefinder. Figure 4 In the figure, the wavy structure on the guide rail is an accordion cover, which is used to keep the corresponding guide rail clean.

[0051] A cross-guide rail structure is used between the first rangefinder, the second rangefinder, the third rangefinder, and the fourth rangefinder, that is, the four rangefinders. The distances of the four rangefinders in the X-axis and Y-axis directions are changed simultaneously. In this way, the detection of four battery cells can be completed at the same time. The number of times the detection axis moves is about half of the original structure, which compresses non-operating time, effectively improves the detection efficiency of the equipment, and reduces the equipment's beat.

[0052] The X-axis driving element and the Y-axis driving distance can both be composed of cylinders. The X-axis driving element can drive the linear slider of the first X-axis moving component to move along the corresponding linear guide toward the X-axis, and the Y-axis driving element can drive the linear slider of the second Y-axis moving component to move along the corresponding linear guide toward the Y-axis.

[0053] In addition, in a specific implementation, the first X-axis moving component, the second X-axis moving component, the first Y-axis moving component, and the second Y-axis moving component can all be linear modules.

[0054] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
